Re: QueryDatabaseTable - Schema

Hi Uwe, I had a similar expectation when I was using QueryDatabaseTable or any other processor creating Avro FlowFile which has its schema embedded, combining new record reader/writer controllers. Now, NiFi has "Inherit Record Schema" option as "Schema Access Strategy" of RecordWriter, already

Re: Unable to restart nifi service

Jim, Would recommend you grab a thread dump and see what the 'main' thread is doing. (kill -3 ) or (bin/nifi.sh dump thread-dump.txt) or (jstack ). That will tell you what it's doing. Thanks -Mark On Sep 11, 2017, at 2:39 PM, James McMahon >

Re: Unable to restart nifi service

I have nearly 1000 prov.gz files in my provenance_repository. Could it be that the system is taking a long time to restore flowfiles to state? On Mon, Sep 11, 2017 at 2:23 PM, James McMahon wrote: > my oversightsorry0.7.x > > On Mon, Sep 11, 2017 at 2:22 PM, Joe

Unable to restart nifi service

About a half hour ago my Nifi UI hung, and in the log I found this error: ERROR [Provenance Repository Rollover Thread-2] o.a.n.p. PersistentProvenanceRepository java.lang.OutOfMemoryError: GC overhead limit exceeded I was unable to get the UI to respond. I went to my command line and executed

Hi, Can i deploy NiFi instance in any other server like Tomcat instead of embedded jetty. Please provide me steps or documentation to configure it. Thanks, Kumar

QueryDatabaseTable - Schema

Hello,   I was wondering why if the QueryDatabaseTable processor creates internally an Avro schema, why is this schema not available as an attribute or saved to the registry?   If it would, then one could reuse the schema. E.g. if I use the ConvertRecord processor and I specify an AvroReader
